Windlass Locker Refit: Epoxy is Your Friend

Rot is insidious. It sneaks in quietly, eating away at the structure of your boat. Mike and Melissa on s/v Galapagos discovered the rot monster eating away at their anchor locker - this is how they defeated it:
When we bought Galapagos we were kind of enthralled with our Lofrans electric windlass. It’s a love affair that continues to this day and because we love her, we want her to live in a nice place. Long ago we noticed that her locker on the foredeck had seen better days. It looked to me like there was wood rot underneath her foot switches and a couple of times when we pulled up anchor, Mike saw the floor of the locker move a little bit. This gave us pause.




So it came to pass that we decided we better get to it and refurbish that part of the boat. This has been one of those projects that takes much longer than you’d like, simply because there are a lot more parts to it than you think, and because Mike still works for a living. That leaves the weekends. And me.

Mike pulled the windlass off and carried her home to take her apart and make sure all of her parts were shiny and new looking and give her a general going over. He can write about that part soon. The windlass has always worked great and we want to keep it that way considering that pulling up anchor by hand on this boat, even given the hand ‘crank’ we can use, would cost a lot in terms of energy, time, and effort. Whatever needs to be done to keep this windlass in good shape is time and money well spent.



When we examined the wood under the switches it was clear that there was not only rot, but that there was a lot of it. If it were not for the fact that this entire locker is hell for stout, we would have had a bigger job on our hands. The wood in this area is about 10” thick meaning you can have a lot of rot before things start getting serious. That also means that after I removed all the rotted wood, we still had plenty to work with. We decided we did not need to remove the entire floor (thank you, gods of windlass lockers!) and that we could fix the area with a series of epoxies, from the liquid kind that soaks into wood to give it new structure, to the kind you smear on like wood putty.

After drilling holes all over the place to make sure we found all the rot, and a good thing we did, too because water came out of some of the holes, we waited as everything dried out in the hot summer sun. Then, over a week or so we mixed batch after batch of System Three End Rot liquid epoxy and their wood putty version called Sculp Wood. When we ran out of the End Rot stuff, we used the straight System Three liquid resin epoxy. We poured the liquid stuff down into the holes and let it seep into the surrounding wood on the topside. When that was cured, we poured in more. We added fiberglass fibers to thicken the paste and troweled it onto the inside of the locker from below, filling in gaps left by the wood we removed. It was a long process that involved a lot of boat yoga, waiting, and sanding in close quarters.


You may be wondering how rot got involved with this windlass locker in the first place. Two reasons became apparent. Let the first reason be a cautionary tale about being sure you are bedding your screws with butyl tape or the equivalent if they are going to be exposed to water. On our two foot switches, the screws holding one switch onto the wood were bedded with something that protected them from water. The screws on the other side were not. So one side had rusty screws, proving that water was ingressing in that area. The wood around that switch was where the rot started and it spread from there. Of course, it’s probably been 20 years or more since those switches were installed. Let’s keep things in perspective here.

Second, the drainage in this locker was poorly designed in our opinion. I don’t know about you, but I don’t think that drains that are above the level where water stands make sense. Think about it. In your sink, the drain is installed slightly lower than the bottom of the sink. That’s because water runs…..down. Not up. So a drain that stands proud of the surface will never, due to the laws of the physical universe, drain all the water out. Standing water is a bad thing, especially if it is close to electric switches installed with unbedded screws. Voila, rot.


So Mike decided to redesign the drains making them much simpler, and making them drain correctly. You know how when people are married for a long time they start thinking alike? We both came up with the exact same idea independent of each other. When that happens, it’s a go. So instead of reinstalling the drains as they were, he filled in the hole where they would be set, cut off the top of the drain that was too high, then drilled out an area and epoxied the drain directly into the hole. Then he attached the hose. It’s not going anywhere and it drains really well now. Plus with all that epoxy the wood will stay protected long after we’re dead. We are considering this simple solution for some other areas of the boat.


When all the epoxy was cured, he sanded everything smooth on top and on bottom. I followed behind him with two coats of bilgecoat, since this area is protected from UV rays unless the locker is open. Although I didn’t bother with a photo yet, the inside of the locker has a nice smooth ‘ceiling’ now. Our windlass will be much happier in her newly refurbished digs. And we have a locker that will see another 25 years in good shape. Stay tuned for part two, where Mike fills you in on the insides of the windlass. Or something like that.

Sailor, and now Author


Drew, a frequent contributor to Practical Sailor and to this blog, has branched out - he is now a published author!  Aside from making a few bucks to cover his time and effort in producing these books, Drew is paying it forward; he is giving new and less-experienced sailors the benefit of his extensive experience.

Drew, as an engineer (disclaimer:  as am I), has a precise, unambiguous writing style.  But he will also wax poetic, in the fashion of a man who has carefully examined his own motivations.

What is rare in the sailing genre is that Drew, again being an engineer, does not shy away from experimentation.  He does not accept "everyone knows" without actually testing it himself, rigorously.  What Drew reports is derived from first person experience and experimentation.  If he says it, he's tested it, and you can believe it.

So far, there are four books in the bookstore:
  • Keeping a Cruising Boat on Peanuts
    PDF, Pending 2017 Kindle, about 400 pages
  • Rigging Modern Anchors
    Pending 2017, TBD, about 250 pages.
  • Singlehanded Sailing for the Coastal Sailor
    Kindle, 143 pages, PDF, 154 pages
  • Faster Cruising for the Coast Sailor
    PDF, 183 pages, Pending 2017, Kindle, about 200 pages

To provide a little view into what's included, here is the Table of Contents from Singlehanded Sailing for the Coastal Sailor:

Valkyr’s Hard Dodger

Scott aboard s/v Valkyr needed more solar power to run his A/C (he is in Florida).  And shade is also a very nice thing...  So he took on the project of making a hard dodger to support all those new solar panels.  This is not strictly a small boat project, but shows some excellent construction techniques.  Enjoy!
So I thought I had posted pictures of Valkyr’s hard dodger long ago but it seems that I didn’t. These are not the best formatted pictures but should help to give an idea of what I did.

aft starboard view boat and dodger
Starboard view of whole dodger frame

dodger aft view handrail and boom protector mounts
We had 1/4 inch aluminum plates welded into frame to bolt the top rails onto. In finished dodger this is what actually holds it to dodger. There are 6 of them.

dodger aft view 1
Aft partial view of dodger frame

Drilling coring filling mount holes 7
We drilled the holes to mount frame to boat and then filled with epoxy and drilled again to make sure we would never have an issue with water penetration into the core.

deck mount and backing plates for under the deck
This is picture of the above deck mount and two of the backing plates for under the deck. As you can see the deck mount has a pivoting base. The reason we went with this is that once mounted we could unbolt the entire dodger with four bolts, and have no risk of water ingress while it is off the boat. also 4 bolts vs 16 bolts is a lot quicker and easier.

Underside of one of backing plates for top rails.

aft port side view of whole dodger

aft starboard view down dodger
starboard view down top of frame. You can see the next attachment point at the center of the handrail and then forward attachment point. Dodger has 3 rails, hand rails on either side that are full length of dodger and attached with 12 1/4 inch stainless bolts. I’m almost 200 lbs and can yank on a rail as hard as I can and it barely shivers the dodger. More rocks the boat the the dodger. The third rail is what you can see in the left foreground of the picture and is simply to keep the boom from hitting the dodger if it falls and for tieing it down if you need to.

visibility sitting at helm looking under dodger
We spent a lot of time making drawings and sitting on the boat taking measurements to get the height of the dodger correct. This is the view sitting at the helm. You have clear unobstructed view under and if you stand up you can see over it. We also did a lot of different version of the side supports to finally end up with the graceful design we got. The curves added strength and elegance yet still left us with a lot of unobstructed view forward under the dodger. The top of the dodger has the same camber as the deck under it.

dodger pad mounting 7
dodger bolted down with sealant.

dodger pad mounting 1
sealant to keep water from running down the bolt.

dodger pad mounting 6
again sealant to keep water from running down bolt. All epoxy filled holes through deck were counter sunk to allow the built up sealant around bolt here to fill and compress in the holes.

dodger pad mounting 8
It took several go around over a few days to fully tighten down. The sealant we used was pretty thick and it would gradually ooze out as it sat after being tightened. After a couple go arounds it was all good and hasn’t leaked in the 4 years since it was installed.

Waterproof junction box
This is a bit out of order but has to do with dodger. This is the central junction for all the solar panels on the dodger near the starboard aft leg of the dodger that the main wires from it run below to the charge controller. We used a water proof document case that we modified into a junction box. notice all wires into have a drip loop. All exposed wire and buss bars are coated in di-electric grease. 4 years later it still looks like new. No corrosion.

Wires from solar panels penetrating dodger top
You can see the deck penetrations where the wires from the solar panels penetrate the dodger. It was a lot of work drilling and then filling all the holes with epoxy and then drilling again. We actually glued the wires to the underside of the dodger in neat runs to lead to the junction box. It has also worked well.

solar panels1
Solar panels on dodger roof. We used a adhesive sealant to attach them to roof. It has held really good. Forget what it is called, something kevlar 400? from PPG.

solar panels2
another view of solar panels. Each one of the panels is 25 watts. They are a thin flexible panel that it is safe to walk on. There are

junction box closed
junction box closed

wire runs to junction box
roof penetration for solar panel wiring and runs glued to roof as they go to junction box. I used quick set gel super glue to do the gluing. Run a line of glue and press wire into it for a few inches and hold for 15 or 20 seconds and then repeat. It took a while to do it all but in the end it was very neat and held good. when I painted it is hardly noticeable under there. Sadly I should have sanded before glueing the wiring in. Not that it was an issue with the wiring but some of the paint flaked off on the under side.

underneath of dodger
another view under dodger. If you notice the chips in the white paint on the aft upper edge of the dodger, That edge takes a beating sometimes an has to be touched up on a regular ( annual basis )

butyl mastic used to seal under the hand rail pads.
Hand rails being attached to the top of dodger once roof is installed.

Hand rails installed
Picture with 12 panels attached. For some reason I think I added a 12th panel behind the aft most two panels for a total of 275 watts on the dodger. There is another 190 watts in one big panel on the dingy davits also for a total of 465 watts on the boat. We had power hooked up at the dock when we lived on the boat to run the AC. Since then though the boat has been powered by the installed solar. We turned off the dock power to save money and never noticed the difference.

forgot to mention. If you look in the lower left corner of the dodger you will notice a drain. We custom made drains in all 4 corners of the dodger with 1/2 inch hose leading down on deck from it. No matter what angle of heel rain will drain off and if we wanted we could lead it to the tanks.

Good view of the aft rail that protects solar panels and dodger top from boom if it falls.
